I agree on the sounds, it was one of the things that people had negative feedback on after watching the trailer(not sure what I was thinking on that Knight slash sound, must've been late at night ). I do have a stock sound pack that I play around with in audacity to create the SFX for the game but that's as far as my expertise goes sadly.

Is there any specific sound you had in mind as reference for the hit sounds?

I've been putting together a text "engine" for my game so I can use fonts that I make in Photoshop rather than plain text that I have been using up until now. It's also useful to display symbols like button icons and such. A little demo of what it does:

I am skeptical that test font would fit Jarvis but we'll see where it goes from here.

I'm liking the water effect and the backgrounds are looking really nice. Are those candles or lights? Just wondering because they're upright and open like candles but have like a stationary bulb, colour, and strobe of a light? Thinking that if they were candles, the flame would maybe move around and flicker randomly as when you get 2 side by side, they seem almost the same pattern wise?.. I was just checking out the other pages and the characters are looking awesome as well!

Man, if you can spend months working on a project, you can make sure your work is properly protected. If Jarvis is trademarked (easy to check, do a trademark search) you need to heed this advice and change the name. Look at all the Tetris-like games killed by the Tetris Company.

To be super blunt - there isn't anything special about the name. Use the opportunity to make something yours and trademark it.

I like the look of your game, but is this an incredibly rare instance of "not enough screen-shake"? In my opinion, most developers posting here are way, way too heavy handed on the screen shake, but I think your attacks would have more meat if there was a subtle screen shake when they connect.
